I recently launched my sailboat, a Half Tonner racing yacht, equipped with the new Epropulsion POD 3kW electric motor. After initial tests, I was genuinely impressed by its performance!
As a reminder, my boat is a Half Tonner racing sailboat.
Exceptional torque and ease of maneuvering
The torque is outstanding—I could stop the boat instantly at the dock using just 30% reverse thrust! Maneuvering within the marina required only around 700 watts. Although my GPS wasn’t connected for accurate speed measurement, I estimate achieving over 4 knots at about 1000 watts.
Quiet and smooth operation
Operating the motor is extremely comfortable, thanks to its nearly silent performance. Additionally, the side-mounted throttle is intuitive and practical, making docking and departing hassle-free.
Estimated battery consumption
Based on initial usage, it seems that approximately 5% of battery capacity is sufficient for typical port entry or exit maneuvers. This efficiency significantly extends battery life for longer trips or extended cruising.
Performance in challenging conditions
Although my initial tests took place in calm weather, the motor’s handling characteristics give me confidence that it could easily handle adverse conditions—such as 20 knots of wind and choppy seas—allowing safe passage out of narrow marina channels, exactly what I was looking for.
Marine paint protection for long-term immersion
To ensure longevity and protection in constant water immersion (365 days/year), I applied:
- 4 coats of Hempel antifouling specifically for submerged sections.
- 2 coats of Primocon primer
Question : How often should the anode be replaced ?
E-NAVSYSTEMS answer : Anodes must be replaced once they show significant wear. Replacement frequency varies depending on usage and environmental conditions (saltwater or freshwater). Regular inspections at least once per year are recommended.
Question : What sealing solution is recommended between the motor housing and interface plate ?
E-NAVSYSTEMS answer : E-Propulsion recommends using Sika adhesive sealant rather than a removable joint. The recommended sealing kit reference is N3-LU04-00.
I’ve included initial images of the installed motor below. More detailed photos, including the internal electrical setup, will follow once the installation is fully completed.
